I have a newly decorated room, and installed polystyrene coving to finish off the look. I have used filler for the joints and sanded down.
However now I can see in certain light where I have sanded down and the filler is a slightly yellower colour than the coving.
I'm wondering if you can paint the polystyrene coving, and if so how you would go about it? Would it need a primer? Or can I just go to gloss? Or would this just soak straight in? Couple of coats?
Any advice please! Thanks.
